Abstract

Usage: in the building materials industry, primarily for the production of clay; The powder used for the manufacture of ceramic products The essence of the invention: at the ends of a circular horizontal central gas duct, one by one there are one branch pipes 8, 9 with inside them with the ability to control the speed of rotation of the rotating elements 10, 11. The cylindrical nozzles 12, 13 have a diameter smaller than the diameter of the central duct, and form an annular gap 14, 15, communicating with the ducts 16, 17 with a hopper 7, equipped with a nozzle for suction of a part of the gas 2 silt

Description

The invention relates to a technique for precipitating a powder after grinding it; it can be used industrially; construction materials, primarily to produce clay powder used for the manufacture of ceramic products.

The known inertial apparatus of the precipitation system of the grinding plant contains a round horizontal central duct, covering its inlet duct, distribution chamber and hopper, while it is equipped with vertical ribs installed along the inlet duct on the inner side of its outer wall, and a dissecting concave sheet installed in the end of the inlet duct in the distribution chamber, the outer wall of the inlet duct being eccentrically

; in relation to the inner wall, made common with the central gas. ; 1J.i. A disadvantage of the known technical. ;; These solutions are increased G: energy consumption due to the unwinding of: a dust and gas stream exiting; from a circular horizontal central gas duct, moreover with a frequent one;: a flow directed to the central gas duct, individual particles of powder fall, which reduces the efficiency of dust deposition

The purpose of the invention is to reduce i energy consumption and increase the efficiency of dust deposition by using the energy of twisting of the dust and gas stream and two-stage cleaning it.,

The goal is achieved by the fact that in the inertial apparatus precipitator00

of a grinding mill system containing a round horizontal central gas duct, covering its gas duct with vertical ribs installed along it on the inner side of its outer wall, eccentric with respect to the inner one, made with a common central duct, JQ distribution chamber with dissecting concave sheet installed at the end of the inlet duct, and the hopper, according to the invention at the ends of the circular horizontal central duct, coaxially to it, -jg installed one bypass pat cans with integrated rotary elements inside the latter, adjustable with rotary elements, equipped with cylindrical nozzles 20 with a diameter smaller than the diameter of the central gas duct to form annular slots in communication with the hoppers equipped with a nozzle J to suck out part of the gas. 25

In Fig.1 presents a General view of the device, in Fig.2 - section aa in Fig "1"

The apparatus contains an inlet duct 1, the outer wall 2 of which has 30 vertical ribs 3 and is made ex-; centrically with respect to the inner one, which is common with a circular horizontal central duct 0 Under the latter there is a distribution chamber gg 5, in the upper part of the chamber, at the end of the inlet duct 1 a dissecting concave sheet 6 and a hopper 7 are installed. At the ends of the circular horizontal central the flue gas t 40 coaxially mounted with branch pipes 8, 9 with built-in inside them with the ability to regulate quick-; these rotations by the rotating elements 10, 11, equipped with cylindrical 45 nozzles 12, 13 with a diameter smaller than the diameter of the central gas duct h, with the formation of annular slots, 15 communicating with the gas ducts 16, 17 with a hopper 7 equipped with a nozzle gn 18 for suction of a part of the gas, and The purified gas is guided through the connecting pipe 19.

The device operates as follows.

Dust-gas flow The inlet duct 1 passes, under the action of inertial forces, its particles rush to its outer wall 2 and fall into

slots formed by vertical ribs 3, and with a small amount of gas being cut off by a concave sheet 6, are discharged through a distribution chamber 5 to a hopper 7 where powder particles settle, m, e0, the first cleaning stage is performed. After that, the flow rises upward towards the cut-off concave sheet 6 into the aperture in a circular horizontal horizontal flow 0 Since the outer wall 2 of the inlet gas duct 1 is eccentric, a gas duct with a variable cross section is created, which tapers at the outlet, which increases the speed of the dust and gas the flow, reduces its turbulence, in addition, the installed vertical ribs 3 eliminate the transverse Taylor-Gertler vortexes, and the diverted most purified gas stream eliminates the capture of small particles Rosca from the hopper 7,

Further, the stream entering the central gas duct kt due to the rotating elements 10, 11 is given such a speed at which through central slots lA, 15 separation of powder particles remaining in the stream takes place. The purified gas is discharged through the connecting pipe 19o

Technical appraisal and economic advantages of the proposed apparatus compared to the known ones consist in reducing energy consumption for cleaning the stream, in increasing the efficiency of dust deposition with a corresponding improvement in the environmental factor, in addition, the possibility of using suction elements in one device makes it possible to obtain two-stage stream cleaning and exclude intermediate flues, thereby reducing hydraulic losses and metal consumption of the entire line ",
